Chrome plated. CNC billet aluminum high performance rear caliper; complete with bracket. Compatible with 11.8" diameter brake rotors and ABS or non-ABS applications. The 3D caliper bodies are engineered for form and function since the sculpted design provides an extremely rigid structure under braking stress. It also helps facilitate cooling with fins that are machined into the inner caliper halves to help effectively disperse heat. Each caliper kit includes brake pads; bleeder screw; banjo bolt; sealing washers; mounting hardware and a shim kit. Note: Bikes with 11.5" rotors must separately order 11.8" diameter brake rotors in order to use these 11.8" brake caliper kits.
